Detect via javascript whether Silverlight is installed

问题

Is there a javascript function I can use to detect whether a specific silverlight version is installed in the current browser?

I'm particularly interested in the Silverlight 2 Beta 2 version. I don't want to use the default method of having an image behind the silverlight control which is just shown if the Silverlight plugin doesn't load.

Edit: From link provided in accepted answer:

Include Silverlight.js (from Silverlight SDK)

Silverlight.isInstalled("2.0");

Please actually use the latest script available at http://code.msdn.microsoft.com/silverlightjs for the latest updates. This has several fixes in it.

回答3:

var hasSilverlight = Boolean(window.Silverlight);

var hasSilverlight2 = hasSilverlight && Silverlight.isInstalled('2.0');

Etc....

回答4:

Download this script: http://code.msdn.microsoft.com/silverlightjs

And then you can use it like so:

if (Silverlight.isInstalled) { alert ("Congrats. Your web browser is enabled with Silverlight Runtime"); }

        if (Silverlight.isInstalled("1.0")) {
            try {
                alert("Silverlight Version 1.0 or above is installed");
            }
            catch (err) {
                alert(err.Description);
            }
        }
        else {
            alert("No Silverlight is installed");
        }

from this video.

Silverlight.isInstalled is always true so version string such as "1.0" must be provided to make it useful.
